WARNING
If you supply your own hoses and spray gun, be
sure the hoses are electrically conductive, that the
gun has a tip guard, and that each part is rated for
at least 3000 psi (210 bar, 21 MPa) Working Pres-
sure. This is to reduce the risk of serious injury
caused by static sparking, fluid injection or over–
pressurization and rupture of the hose or gun.
CAUTION
To avoid damaging the pressure control, which may
result in poor equipment performance and compo-
nent damage, follow these precautions:
D Do not allow material to freeze in sprayer.
D Use nylon spray hose at least 50 ft (15 m) long.
D Do not use wire braid hose.
D Do not install shutoff device between sprayer and
gun. See Fig. 2.
1. Connect hose (B) and gun (C) and screw it onto
outlet nipple (A). Don’t use thread sealant, and
don’t install spray tip yet!
2. Fill packing nut (D). Fill packing nut full with
Graco Throat Seal Liquid (TSL) (64) supplied.
WARNING
FIRE AND EXPLOSION HAZARD
Proper electrical grounding is essential
to reduce the risk of fire or explosion
which can result in serious injury and
property damage. Read FIRE OR EX-
PLOSION HAZARD on page 4 and
Grounding, page 7.
3. Plug in sprayer. Be sure ON/OFF switch (E) is
OFF. Plug cord into grounded outlet at least 20 ft
(6 m) away from spray area.
4. Flush pump to remove oil installed to protect
pump parts after factory testing. See page 12.
5. Prepare paint according to manufacturer’s recom-
mendations. Remove any paint skin. Stir paint to
mix pigments. Strain paint through a fine nylon
mesh bag (available at most paint dealers) to
remove particles that could clog gun filter or spray
tip. This is an important step toward trouble-free
paint spraying.
